Multi-destination path navigation method

Abstract

The invention discloses a multi-destination path navigation method, comprising the following steps: a) selecting an interest point through a mobile terminal to serve as a destination, sending a path navigation request to a server, and calculating a first navigation path through the server with the destination as end point; b) searching interest points with the same name or category within a preset range on the surrounding of the destination through the server; c) if interest points with the same name or category exist, using all searched interest points as end points, and continuing to calculate the navigation path to obtain a plurality of second navigation paths; d) respectively comparing the plurality of second navigation paths with the first navigation path, and if a second navigation path with better pre-estimated distance or pre-estimated time obviously exists, simultaneously sending the second navigation path and the first navigation path to the mobile terminal for selection. By adopting the multi-destination path navigation method provided by the invention, detour or time waste caused by improper destination selection of a user is avoided, and the navigation efficiency is greatly improved.

Description

technical field [0001] The invention relates to a path navigation method, in particular to a multi-terminal path navigation method. Background technique [0002] When selecting a navigation destination, there are often multiple destinations for unclear place names. For example, if you also search for "A service area" or "B service area", you can often find that there are actually two POIs with the same name on both sides of the expressway. Although they are very close to the two POIs with the same name, they use different As the destination, the calculated distance will be quite different. For example, assuming that the "A service area" in the direction of the vehicle's navigation is the destination, the route may be only a few hundred meters, while the "A service area" in the opposite direction of the vehicle's navigation "For the destination, you may need to detour for several kilometers or even more than ten kilometers. Therefore, it is necessary to provide a multi-dest...
